I'm trying to visualize your situation. Roll with me on this hypothetical:
1) You set up a target at 50 yards.
2) You put your crosshairs on the center of the bullseye and shoot three rounds.
3) Those three rounds impact, roughly, in a group 4 inches above your point of aim at the bullseye.
4) Are you not able to turn the scope's elevation knob to drop the point of impact four inches so that your next three rounds group on the bullseye at point of aim? If your scope has 1/2 MOA click adjustments, would that be 16 clicks at 100 yards and 8 clicks at 50 yards — if my math is correct?
I'm trying to picture what you're experiencing, but I feel like I'm missing something.
Anything is possible, so if it's a barrel issue I see two possibilities: 1) the bore was drilled incorrectly and off-center within the barrel axis, or 2) maybe the extension was sorta cross-threaded and thus installed at an angle. So let's do the math on those two possibilities:
If you aim at the bullseye at 50 yards and your shots impact 35 inches high cuz the barrel or bore is canted and you thus run out of scope elevation, trigonometry says your bore is at either a 1.146° angle to the barrel axis or your barrel is canted 1.146° relative to the barrel extension. See attached schematic.
If it's a barrel issue, I would think your barrel would look like one of the two schematics.
If your barrel doesn't look like that, then it would be simplest to test the point of impact with a different scope altogether or even iron sights. You could also try that Vortex scope on another gun and see if anything's changed.
